あるページ (API ページ) には、次のような PHP 配列があります。
$arr = array("headline1" =>
array("name" => "Headline 1",
"description" => "Description of headline 1",
"items" => array(
array("name"=>"John", "lastname"=>"Doe"),
array("name"=>"Peter", "lastname"=>"Pan")
)
),
"headline2" => array("name" => "Headline 2",
"description" => "Description of headline 2",
"items" => array(
array("name"=>"Alexander", "lastname"=>"Doe"),
array("name"=>"Steven", "lastname"=>"Smith")
)
),
"headline3" => array("name" => "Headline 3",
"description" => "Description of headline 3",
"items" => array(
array("name"=>"John", "lastname"=>"Doeh"),
array("name"=>"Peter", "lastname"=>"Pans")
)
)
);
そして、この配列から、スクリプトは json でエンコードされたバージョンを作成します。
echo json_encode($arr);
だから、私の問題は他のページのjavascriptにあります。jQuery $.getJSON 関数を使用してこのデータを取得し、次のように var を作成します。
var categoryData = {
headline1: {
name: "Headline 1",
description: "Description of headline 1",
items: [
{
name: "John",
lastname: "Doe"
},
{
name: "Peter",
horoscope: "Pan"
}
]
},
headline2: {
name: "Headline 2",
description: "Description of headline 2",
items: [
{
name: "Alexander",
lastname: "Doe"
},
{
name: "Steven",
horoscope: "Smith"
}
]
},
headline3: {
name: "Headline 3",
description: "Description of headline 3",
items: [
{
name: "John",
lastname: "Doeh"
},
{
name: "Peter",
horoscope: "Pans"
}
]
}
};
jQuery $.getJSON関数でこれを達成するにはどうすればよいですか?

// Now call changePage() and tell it to switch to
